Dodecad submission opportunity

I took some time to re-organize some of the Dodecad populations, as part of the current submission opportunity.

For example, I extracted an English_D population out of the previous British_D one; the latter now contains all British individuals that don't have four English grandparents.

Many ethnic groups were represented in the Indian_D population, and I extracted at least two samples, Iyer_D, and Jatt_D with at least 5 participants each.

I've also identified a few other smaller populations, such as Breton_D, Turkish_Cypriot_D, which haven't reached 5 participants yet, but I'm hopeful that they will.

In any case, here is the list of current Dodecad populations. Do consider submitting your data to the Project, especially if you belong in one of the populations that haven't reached 5 participants yet, or in one of the eligible groups that are not represented in the Project. Even groups with relatively large sample sizes could use more participants: more data = better ability to discover patterns of human variation.

I hope you include in the Dodecad Turkish Cypriot population only people whose all four grandparents are Turkish Cypriots. I mean, many people from Turkey migrated to Northern Cyprus during the last few decades, largely as a result of the policy of increasing the Turkish population of the island of Cyprus. Those migrants and their descendants, whether partial or full, should be excluded from the Dodecad Turkish Cypriot population. Turkish Cypriots have a peculiar Turkish dialect, a peculiar accent and, more importantly, a uniquely Cypriot culture, so they deserve to be investigated separately.

I see the Spanish samples are increasing, and several individuals show interesting regional features, as for example Galicians, Northeast Iberians or Southern Spaniards. Perhaps not all of them have 4 grandparents from an especific territory, but having at least 3 it's enough to see characteristic proportions.

Sorry, but not true at all. I am from North Ossetia, living in US. As soon as I was able, I purchased a DNA kit for my son from 23andMe. Another test, my daughter's, is in the way. Don't know about other websites, but FTDNA has many members. People from North Caucasus Do buy genetic tests. North Ossetians for sure.

My question was very simple. Why you don't represent North Caucasus in your programs? The answer, that they don't buy genetic test is wrong, but you probably right about not providing data. I will send my son's today. I will send my daughter's as soon as I receive. I'll ask other ones I know already having results to send it to you also. But that would be Ossetian only. I truly want to know the real origin of Ossetian. There are too many theories. Ossetians are different among themselves. They have three dialects.But thank you for your work. I really enjoy reading your blog.
